PNP Matched Pairs

[Tony Allgood]

>The SSM2220P part number...

Farnell sell the SSM2220P in the UK. I am using it as an expo in my
latest project.

Plus, don't forget the NPN pair; the SSM2210

I love these, as all purchasers of either of my two pcbs will testify.
The TB3030 expo has one, and the Moog ladder has two for top and bottom
pairs. In the UK Maplin and Farnell both sell them.

I have enquired at Analog Devices whether there will be any production
problems with these in the future... here today, gone tomorrow scenario.
But they wouldn't give me an answer over e-mail. I had to ring their
free data helpline, fine if you are in the US, but not if you are based
in the UK. Would anyone like to find out for me?
